SHUTTLE-BOX-ACTUATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 786,232, dated March28, 1905.

Application filed November 14, 1904. Serial No. 232,595.

10 all whom it may concern:

Be it known that I, ANTHONY J. ORETLLY, a citizen of the United States,and a resident of Worcester, in the county of Worcester and State ofMassachusetts, have invented an Improvement in Shuttle-Box-ActuatingMechanism, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object to im-- prove and simplify theactuating mechanism for shuttle-boxes in looms.

The improvements herein to be described I 5 and claimed are directedtoward the class of shuttle-box-actuating mechanism wherein a vconstantlymoving partial gear engages a tooth on one or another leg of aforked gear that is slid automatically in a mutilated pinion to placeone or the other of said teeth in line with the teeth of said pinionthat the teeth of the partial gear in its rotation may meet the tooth ofthe forked gear then in its operative position and impart a semirota- 25 tion to that pinion and the shaft carrying the same to move theshuttle-box lever up or down. The partial gear having engaged a tooth ofthe forked gear moves the latter and the mutilated gear and imparts tothe 0 shaft a semirotation.

In accordance with my invention I have providcd'novcl means forarresting the mutilated gear and its shaft at the completion of eachsemirotation, thus causing the lock- 5 5 ing of the gear and theshuttle-box moved by it in its correct relation to the race of the lay.

My improved stop is so constructed as to be met by that tooth of theforked gear which is in its inoperative position or out of line withrelation to the teeth of the mutilated gear.

The stop is yieldingly sustained.

Figure 1 in end view shows a shuttle-boxactuating mechanism embodying myinvention. Fig. 2 is a front sideview of most of the parts shown in Fig.1, and Figs. 3 and 4 show details in perspective illustrating the forkedgear in its two extreme posit ons.

Referring to the drawings, A represents part of the end frame of aloomprovided with suitable bearings for sustaining a cross or cam shaftA, provided with a partial gear A The end frame of the loom sustains astand B, having bearings for a shaft B, provided at its inner end with adisk B having a crank-pin B that receives the hollow hub at the end of alink B that is ointed at its upper end, as shown only in Fig. 1, to therear end of a shuttle-box lever B. The disk has inwardly-directed pinsa, and said shaft has keyed thereon outside the bearings a mutilatedgear O, said gear having some of its teeth cut away oppositely and beinggrooved to receive the legs d d of a forked gear D, the leg d having atooth d, while the leg cl has a tooth (i The outer end of the forkedgear is shown as grooved to receive a stud at the lower end of anactuating device, shown as an elbow-lever D, pivoted on a stud D' andhaving slipped over its opposite end part of a connecting-rod D, that isextended upwardly to a finger coacting with usual pattern mechanism tomove the rod, turn the lever, and slide the fork, according to which oneof two boxes carried by the shuttle box lever B is to be put intooperative position with relation to the raceway of the lay. The parts sofar described are common to looms for moving shuttle-boxes.

In accordance with the invention to be herein claimed I have providedthe framework with a stud e, on which I have mounted a stop E, saidstop, as herein represented, having two arms 6 6 the part c of the stopextended to the left, viewing Figs. 1 and 3, having a projection a onwhich rests the E, as shown in Fig. 3.

lower end of a spiral spring 6, (shown by dotted lines in Fig. 1,) theupper end of said spring resting against a fixed ear a, forming part ofthe loom-frame, the spring referred to acting normally to hold the stopyield ingly in its operative positionthe position shown in the drawings.

The spring)", shown as carried by the hub of the lever D, acts normallyto place the forked gear in the position shown in Fig. 3, with the toothd of the leg (Z in line with the teeth 0 of the mutilated gear C.IVhenever the protuberance of the usual pattern-surface (not shown)raises the connection D from the position Fig. 3 into the position Fig.4, the elbow-lever D slides the forked gear into the position Fig. 4,putting the tooth d in line with the teeth 0 of the mutilated gear. Letit be supposed that the mutilated gear C is'at rest, with the tooth d ofthe forked gear arrested by the arm a of the stop E, and that it isdesired to shift or put into position opposite the race of the lay thelowermost box of a series of two boxes. Now a protuberance of thepattern-surface will, acting through the connection D and lever I), turnthe lever and slide the forked gear inwardly toward the loom side,placing the tooth d of the legd in such position that as soon as theteeth a of the partial gear meets said tooth it will start in rotationthe mutilated gear and its shaft B, turning the disk andcrank-pin anddepressing the rear end of the shuttle-box lever B", thus lifting itsopposite end and putting the lowermost box of the two opposite the raceof the lay. The partial gear has sufficient teeth a to coact with one ofthe series of teeth of the mutilated gear to turn the latter and theshaft B a half-rotation, at which time the gear will come opposite theleg (1, having the tooth (I then in its inoperative position, and consequently the partial gear will run out of engagement with the mutilatedgear and the tooth (Z of the leg d will meet the arm 0 of the stop E,stopping the further rotation of the shaftB and positioning accuratelythe shuttle-box lever carrying the shuttle-box as to place the lowermostshuttle-box cell at the race of the lay. New to start the lever againand bring the uppermost box-cell of the two opposite the race of the laythe lever 'D will be turned in the direction of the arrow on it, Fig. 4,by the springf, a space of the pattern-surface permitting, and the toothd of the legd will be put in line with the teeth 0 of the mutilatedgear, and the partial gear in its rotation will engage the tooth andturn the mutilated gear and its shaft B until the tooth d of the leg (1in the rotation of the forked gear meets the arm 6 of the step In thisway it will be seen that first one and then the other tooth of the twoarms (1 and (1 meet first the arm 0 and then the arm of the stop E, sothat the stop acts positively to prevent any overrunning or wrongpositioning of the shuttlebox lever and shuttles. In case of anyaccidental backward movement of the mutilated gear a tooth of the forkedgear will contact with the inclined rear or left-hand side of the arms 6c and the stop may give a little under the spring a and obviate breakingof the parts.

Herein the pins (1 are acted upon by the usual foot a, pivoted at a andnormally held down by a spring Having fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. In a shuttle-box-moving apparatus for looms, the combination with ashaft having a mutilated gear, a coacting forked gear having teeth outof line one with the other, and means for moving the forked gear toplace either tooth thereof in line with the teeth of the mutilated gear,of a stop adapted to be struck by that one of the teeth of the forkedgear which occupies its inoperative position with relation to themutilated gear.

2. In a shuttle-box1noving apparatus for looms, the combination with ashaft having a mutilated gear, a forked gear having teeth at differentdistances from the hub of said gear, and means to slide the forked gearwith relation to the mutilated gear to place either tooth of the forkedgear in its operative position with relation to the teeth of themutilated gear, of a stop having two arms and adapted to stop saidmutilated gear and shaft at each semirotation by acting directly againstone or the other of the teeth of the mutilated gear. i

3. A shuttle-box-moving apparatus, a retatable shaft having a partialgear, a shuttlebox lever, a shaft, means between said shaft andshuttle-box lever to move the latter, a mutilated gear fast on thelatter shaft, a forked gear having legs engaged loosely with saidmutilated gear, each leg having a tooth, said teeth occupying positionsin different vertical planes, means to put either tooth of the forkedgear in line with the series of teeth of the mutilated gear to beengaged by the teeth of the partial gear to rotate the mutilated gearand its shaft for a distance of one hundred and eighty degrees, and astop having two arms, one or the other arm being interposed in the pathof movement of one or the other of the teeth of the forked gear then inits inoperative position to stop said gear at the end of eachsemirotation thus insuring the absolute alinement of the shuttle-boxwith the race of the lay.

4. In a shuttle-box-operating mechanism for looms, the followinginstrumentalities,

viz: a crank-Wheel, a shuttle-box lever, an name to this specificationin the presence of intermediate connector between said crank twosubscribing Witnesses. and lever, a stop device at rest during the operation of the boX motion, and acting to ar- ANTHONY O REILLY 5 restsaid crank-Wheel, as the latter completes l Witnesses:

its full movement. CHARLES F. ALDRICH,
